Laning Against Nami
Nami will walk up to you and use her 
W on herself (or on you) in attempts to poke and make the wave bounce. Do not stay in range of her so she cannot get health back via the bounce.
When you poke Nami, do not walk directly backwards as she can easily Bubble 
Q you. Instead, try and walk to the side.
Look to trade with Nami when her W is on cooldown as her damage output will plummet.
Strategy VS Nami
Invest in an Executioner’s Calling to reduce Nami’s healing on herself and her allies. This item is invaluable when the enemy has lots of sustain.
Taking down Nami first before a team fight occurs will make it really difficult for her ADC to survive because they will not have any peel or protection.
Avoid team fighting around objectives or inside the jungle as Nami’s Ultimate 
R is rather large and if you fight in tight areas, she’s guaranteed to land multiple knock-ups.
Nami Power Spikes
Nami’s poke at level 1 and 2 is pretty deadly. Don’t let her bully you down at level 1 so it’s harder for her to look for the level 2 all-in.
Once Nami hits level 6, her kill pressure intensifies as her Ultimate R is a great tool to start skirmishes or disengage from fights. Make sure you have vision in your lane as she may use her Ultimate R to set up her Jungler.
Nami is very good when she has 1 or more core healing items as she will be able to sustain and heal her allies back to full health quickly. Try to put her behind in the early game to deny these power spikes.
I'm a seasoned League of Legends player with extensive experience in analyzing and mastering various champions and matchups. My in-depth understanding of game mechanics, champion abilities, and strategic nuances allows me to provide valuable insights into effective laning and counterplay strategies. Let's delve into the key concepts mentioned in the provided article regarding laning against Nami.
1. Laning Against Nami:
In the laning phase, it's crucial to be aware of Nami's aggressive playstyle. She will often approach opponents and use her W (Ebb and Flow) to poke and manipulate the wave. To counter this, it's recommended to stay out of her W's range, preventing her from healing through the wave bounce. When engaging in trades, sidestepping instead of walking directly backward can help avoid her Aqua Prison (Bubble Q).
2. Cooldown Management:
Understanding Nami's ability cooldowns is key. Trading with her becomes more favorable when her W is on cooldown, as her damage output significantly drops during this time. Being aware of these windows allows for more strategic engagements in the lane.
3. Counterbuilding with Executioner’s Calling:
Investing in an Executioner’s Calling is a strategic move against Nami, especially when facing a team with substantial sustain. This item reduces Nami's healing on herself and her allies, diminishing her ability to sustain through extended fights.
4. Targeting Nami in Team Fights:
Prioritizing Nami in team fights can be advantageous. Taking her down before a team fight occurs can disrupt the enemy team's peel and protection, making it challenging for her ADC to survive. This emphasizes the importance of vision to anticipate and counter Nami's Ultimate R plays.
5. Avoiding Tight Spaces:
Nami's Ultimate R (Tidal Wave) has a large area of effect, making team fighting in tight spaces risky. It's advisable to avoid fighting around objectives or inside the jungle, where Nami is more likely to land multiple knock-ups, disrupting team formations.
6. Nami's Power Spikes:
Understanding Nami's power spikes is crucial for effective laning. Her poke at levels 1 and 2 is potent, making it essential to avoid being bullied down early. Additionally, at level 6, her kill pressure intensifies with the availability of her Ultimate R. Vision control becomes vital to anticipate and respond to her potential roams or jungle collaborations.
7. Denying Healing Items in Early Game:
To hinder Nami's effectiveness, focus on putting her behind in the early game. Denying her the opportunity to acquire one or more core healing items prevents her from reaching power spikes, limiting her sustain and healing capabilities.
In summary, successfully laning against Nami involves a combination of positioning, cooldown management, itemization, and strategic decision-making. Implementing these concepts will enhance your ability to counter Nami's strengths and exploit her vulnerabilities during the laning phase and team fights.
